Troglodyte roux

Cinnycerthia unirufa

Un troglodyte de taille moyenne, de couleur uniforme, que l'on trouve dans les zones subtropicales supérieures et tempérées des Andes, de l'ouest du Venezuela à l'extrême nord du Pérou. Entièrement brun-roux vif (le plus éclatant chez les populations du nord) avec des lores noires et de légères barres sombres indistinctes sur les ailes et la queue. Similaire au Troglodyte de Sharpe, mais plus brun éclatant et généralement trouvé à des altitudes plus élevées. Il vit entre 2 200 et 3 800 m d'altitude. De petits groupes fourragent dans le sous-bois des forêts, souvent autour des fourrés de bambous. Peut être discret et difficile à bien observer. Suit parfois les bandes mixtes. Écouter ses cris jacassants et rauques.

Identification

The rufous wren has a length of about 16.5 cm (6.5 in). Birds in most of Colombia and in Ecuador are a uniform dark chestnut-brown colour with slight blackish barring on the wings and tail, though this is difficult to observe in the field. The lores are also blackish. Individuals in northeastern Colombia and in Venezuela are a slightly paler shade, especially on the crown. The rufous wren could be confused with the sepia-brown wren (Cinnycerthia olivascens), but that species is less rufous and has bolder barring on wings and tail. Another similar bird is the rufous spinetail (Synallaxis unirufa), but that species has a longer tail, has no barring on wings and tail and is altogether different in voice and habits.

The rufous wren is usually found in groups of a few individuals often joining other species of birds in small flocks.
